Harp guitar
The harp guitar is a guitar-based stringed instrument generally defined as a "guitar, in any of its accepted forms, with any number of additional unstopped strings that can accommodate individual plucking."[3] The word "harp" is used in reference to its harp-like unstopped open strings. A harp guitar must have at least one unfretted string lying off the main fretboard, typically played as an open string.
This family consists of many varieties of instrument configurations. Most readily identified are American harp guitars with either hollow arms, double necks or harp-like frames for supporting extra bass strings, and European bass guitars (or contraguitars). Other harp guitars feature treble or mid-range floating strings, or various combinations of multiple floating string banks along with a standard guitar neck.[4]
Electric harp guitars[edit]
While most players of harp guitars play on acoustic instruments, a few of them also work with electric instruments. Notable artists who played electric harp guitars are Tim Donahue (who uses a fretless guitar section) and Michael Hedges. American musician William Eaton both designs and plays electric harp guitars.[5] The Japanese noise band Solmania built their own harp guitars. Yuri Landman has built a 17 string electric harp guitar for Finn Andrews of The Veils.[6] The instrument has an additional movable bridge on the harp section allowing players to pitch the harp section higher or lower.
